STRETCHER-FRANIE.

Specication of Letters Patent.

Patented Jan. 1, 1907.

To all whom it may concern.:

Be it known that I, ELIZABETH MCCOMBIE, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented new and useful Improvements in Stretcher-Frames. of which* thefollowing is a speciiication. l

This invention is a frame designed for stretching, shaping, or dryingpieces of fancywork, doilies, lacework, embroidery-pieces, and the like,and has for its object to produce an adjustable frame which can bevaried in size and otherwise adapted for use, as will hereinafterappear. f5 In the accompanying drawings, Figure 1 is a plan view of thedevice. Fig. 2 is a section thereoic on the line 2 2 of Fig. 1. Fig. 3is a section on the line 3 3 of Fig. 1.

Referring specifically to the` drawings, 6 indicates a band or hoop ofwood or wood reinforced with metal, having in the upper edge thereof anundercut groove 7, in which lit and slide the heads of a series of pinsS. The pins can accordingly be moved along the groove to any desiredplace. The ends of this hoop are lapped, and the size of the hoop may bevaried by increasing or decreasing the lap. To sustain the hoop and holdit in adjusted position, a diameter-bar is used consisting of twosections 9 and 10, the latter of which slides in a groove in the underside of the former, so that the bar is extensible in length and when setas desired is fixed by a pin 11, which may be placed in registeringholes, of which there lare a series in the respective sections. Near oneend the piece 9 has a pair of wheels 12 and 13 on its upper face, andthe hoop 6 fits between these wheels and has grooves 14 on oppositesides which receive the edges of the respective wheels, whereby the hoopis held down upon the cross-piece, and yet the wheels allow the angularposition of the cross-piece to bevaried when it is'des'ired to enlargeor decrease the size of the hoop.

The piece 10 has at the other end a block 15, to which is secured aclamp member 16,

having a ange 17,boltcd, as at 18, to one end of the hoop 6, and thefreeend of the hoop fits snugly between said ixed end and a segmental outerflange 19. By special effort the free end of the hoop can be pulled orpushed along to vary the size of the frame.

In use the hoop is set to the proper size to accommodate the work, whichis then engaged at its edges over the pins and stretched or dried, asthe case may be. The adjustment of the pins allows irregular pieces tobe engaged by moving the pins to the desired position on the hoop.

claim- 1. A stretcher-frame comprising an expansible hoop having lappedends, and an extensible diametrical bar extending across the 'hoop andconnected to opposite sides thereof.

2. A stretcher-frame comprising a hoop having lapped ends, a diametricalbar formed in extensible sections one of which has a clamp at the endengaging the lapped ends and the other of which is connected to theopposite side of the hoop.

3. A stretcher-frame comprising an expansible hoop having grooves in thesides thereof, and an extensible diametrical bar one end of which isconnected to the hoop at one side and the other end of which has a pairof wheels thereon which project into the said grooves in the hoop.

In testimony whereof I have signed my name to this speciiication in thepresence of two subscribing witnesses.

ELIZABETH MoCOMBIE.
